2 Claims. (01. 99-291) This .invention relates to beverage-making uidcofiee receptacles 6 are provided within the equipment utilizing hotwater, and more particuboiler 5, and suitable foraminous ground coffeelarly to that suitable for the making of coffee and receptacles aresupported within the uppe P similar drinks. tions of, the liquid cofieereceptacles 6, as at I.

pivotally connected to the upper end of switch lever 28 by a pin andslot connection 33.

The rotatable core of valve I2 is shown at 33, and an indicatorincluding a pointer 31 movable with the valve member 36 is provided onthe outside of the casing of valve 12 to show the position of said valvemember 33, so that the desired flow of liquid may be surely obtainedupon operation of this control valve.

In use, water is supplied to boiler 3 and heated by burner 9. By liftingand laterally swinging the cover 8 of the left hand receptacle 3, aground coffee receptacle I containing ground coffee may be placed inposition at the top of said receptacle Ii. The valve I2 is then operatedso as to provide communication between the boiler and pump II by way ofpipes i5 and 20, the valve member 33 being positioned as shown in Figure2. Switch 25 is then operated so that the circuit ofmotor 23 will beclosed, whereupon said motor drives pump for drawing the hot water fromboiler 5 and discharging it through pipe 2| and spout 22 into the top ofreceptacle 6 whose cover has been previously opened and over which thespout 22 has been swung, as indicated by dotted lines in Figures 1 and3. As the hot water will discharge from spout 22 faster than it willseep through the ground coffee in the receptacle 1, the level of liquidwill rise above the latter so that it will act upon the float 3| toraise the associated float rod 29 and swing lever 32 in a direction tocause arm 34 to swing to the left of Figure 6. When this occurs, contact21a is permitted to disengage from contact 21 so as to open the motorcircuit and discontinue the operation of pump H and the supply of hotwater to the left hand receptacle 6. When the level of water inreceptacle I of this left hand liquid coffee receptacle 6 lowers, float31 will lower so as to automatically cause engagement of the contact 21awith contact 21 again, thereby rendering the motor 23 operative againfor resuming the supply of hot water to the left hand receptacle 3. Thiscycle is repeated as long as necessary to complete the coffee brewingoperation, whereupon switch 25 is manually opened, the lid 3 of lefthand receptacle 6 is closed, and spout 22' the way. However, during thiscycle of operation, and a short time after the brewing operation hasbeen'started, the valve l2 will be operated to disconnect pipe 20 frompipe 15 and connect it with pipe l3 of the left hand receptacle 3 sothat in the remainder of the brewing operation, the liquid coffee willbe re-circulated or drawnfrom the left. hand receptacle 6 and returnedto the top thereof through spout 22. In other words, only enough hotwater is drawn from the boiler to make the necessary amount of liquidcoffee in the recepis swung out of tacle 3, the brewing operation beingcompleted by simply circulating the liquid coffee through the coffeegrounds in receptacle 1 until completion of the operation. It whilecoffee is being made in the receptacle 6, coffee may be dispensed fromthe right hand receptacle 6. When desired, the same brewing operationmay be carried on.with respect to the right hand receptacle 8.

From the foregoing description, it is believed that the construction andoperation of the present invention, as well as the advantages thereof,will be readily understood and appreciated by those skilled in the art.Minor changes in the details of construction illustrated and describedare contemplated, such as fairly fall within the spirit and scopeof theinvention as claimed.

What I claim as new is: 1. Beverage making equipment comprising a liquidcoffee receptacle, a ground coffee receptacle in the upper portion ofsaid liquid coflee receptacle, a. boiler, a pump having a dischargepipe, and an electric driving motor, said discharge pipe being adaptedto discharge into the liquid coffee receptacle above the ground coffeereceptacle, pipe connections and a manually operable control valve forselectively placing the inlet of said pump in communication with theboiler or in communication with the liquid coffee receptacle, a,normally closed switch for controlling the circuit of said motor at onepoint, a float arranged in the liquid coflee receptacle above the groundcoffee receptacle and operatively connected to said switch for openingthe circuit of said motor at said point when the water or liquid coffeesupplied by the pump to the ground coffee receptacle fills the latterand rises above the same and for closing the circuit at said point whenthe level of said supplied water or liquid coffee lowers into the groundcoffee receptacle by seeping through the latter, and a manually operableswitch for controlling the motor circuit at another point.

2. Beverage making equipment comprising a boiler, two liquid coffeereceptacles within the boiler, ground coffee receptacles in the upperportions of said liquid coffee receptacles, a pump having a dischargepipe and an electric driving motor, said discharge pipe having ahorizontally swinging swiveled discharge spout movable to discharge intoeither desired one of said liquid coffee receptacles above the groundcoffee receptacles thereof, pipe connections and a manually operablecontrol valve for selectively placing the inlet of said pump incommunication with the boiler or either desired one of said liquidcoffee receptacles, a normally closed switch for controlling the circuitof said motor at one point, floats arranged in the liquid coffeereceptacles above the ground coffee receptacles thereof and operativelyconnected to said switch for opening the circuit of said motor at saidpoint when the water or liquid coffee supplied by the pump to eitherground coflfee receptacle fllls'the latter and rises above the same andfor closing the circuit at said point when the level of said suppliedwater or liquid coffee lowers into said ground coffee receptacle byseeping through the latter, and a manually operable switch forcontrolling another point.
